A guide to help you address and fix basic platform scale problems

1. Inspect and clean beneath the scale?

Debris beneath the scale platform or around the load cells in the scale platform can cause errors in weight readings. For this reason, the easiest fix for platform scale issues is routine cleaning. This includes cleaning the area beneath the scale periodically.

Tips for successful bench and floor scale cleaning in all environments:

• When cleaning beneath the platform, be careful not to move the load cell cables to a position where they could be pinched or cut during operation.
• Scale platform binding is indicated by non-repeatable weight readings. To avoid platform binding, ensure clearance around the platform so it can move freely.

Additional tips for cleaning in washdown environments:

• Water damage is a common cause of failure in load cells. Make sure to use load cells with a suitable IP rating in case of high-pressure or steam cleaning.
• If the platform meets the requirements for washing, pay attention to the temperature of the water used. Elevated temperatures can cause incorrect readings until the scale cools to room temperature.

2. Check the load cells.

There are several load cell issues that can cause a scale’s display to not stay at zero. One possibility is that the load cell connection is faulty. If this is the case, check cable connections at the indicator and the junction box, if present.

If the connections are stable, the scale may contain overload screws which need to be readjusted per the manufacturer’s recommendation or transport safety screws that must be removed before using the platform.

If the scale is consistently showing instability, the load cell cables may be pinched or cut. If this is the case, you may need to replace the load cell or homerun cable if they can’t be repaired.

?3. Recalibrate the scale after testing if needed

After performing all troubleshooting steps described above, test the scale and see if it needs to be recalibrated. If so, contact a certified technician to determine the correct procedure for calibrating the scale.

Reminders for successful platform scale calibration:

1. Power up the indicator at least 20 minutes before starting the calibration to give the system time to warm up.
2. Load the scale to near capacity two or three times before calibration is performed.
3. With the scale base level and no load on the scale, place the indicator in calibration mode and perform a zero calibration according to the indicator manual.
4. Place calibration weights that weigh 75% of the scale’s capacity on the platform and observe the weight reading.
5. Remove the weights and check the zero reading. Repeat the calibration process if necessary.

4. Consult an expert
